"But they have to be on hand 24/7 - for example, we had problems with a bit of weather damage during the strong winds in December."

He added: "It's like a ship at sea because it's governed by the weather and when you're inside it creaks and groan - but it's been here for 200 years and hopefully it will now be here for 200 years more."
